Abstract

A disposable loading unit for use with a surgical stapling instrument is disclosed. The disposable loading unit comprises a cutting member, an anvil, and a first replaceable stapling jaw assembly. The first replaceable stapling jaw assembly comprises a first cartridge body and first staples. The disposable loading unit further comprises a second replaceable stapling jaw assembly comprising a second cartridge body and second staples. The disposable loading unit further comprises a lockout that prevents the first replaceable stapling jaw assembly from being fired after the first replaceable stapling jaw assembly has been at least partially fired. The surgical stapling instrument and the disposable loading unit are configured to deploy the second staples from the second replaceable stapling jaw assembly with which the first replaceable stapling jaw assembly is replaced.
